CX-PG-SP series gauge is suitable for measuring the pressure or vacuum of liquid, gaseous and vaporous media that will not explode, crystallize or corrode the elements, it can send electric signal for automatic control and alarm with some electric devices. 

Series CX-PG-SP with magnetic snap-action contact own large load, stable export, long contact life and some cushioning and dampening effect. 

Besides the features of series CX-PG-SP, series CX-PG-SP -NC offers a significant cushioning and dampening effect and provide a longer gauge life by filling damped oil and installing damped tube, damped piece and damped bolt. With the antivibration structure, it can restrain the oscillation and pulsation of the pointer, protect contact and make the indication and the electrical transformation to be reliable and stable. 

CX-PG-SP and CX-PG-SP NC-BF series filled snap-action contact pressure gauges with corrosion-proof are suitable for measuring the pressure of the media with strong corrosion and offer reliable signal for auto control. 

The products are widely used in mechanical industry, chemical industry, metallurgy, petrochemical, mine, electric power and so on. 

Besides these, CX-PG-SPG and CX-PG-SP NCG series isolation snap-action contact pressure gauges are suitable for high temperature condition (70 ~150º C), and send reliable alarm and control signal.
